Abstract
A ternary metal-rich telluride Pd2NiTe2 has been prepared by the solid-state reaction. This compound crystallizes in the orthorhombic K2ZnO2-type structure with space group Ibam. In this structure, the Ni atom is tetrahedrally coordinated and the NiTe4 tetrahedra share edges forming one-dimensional chains with short Ni-Ni bondings along the c-axis. Through magnetic susceptibility, specific heat, and electrical resistivity measurements, this compound shows Pauli paramagnetism and metallic electrical conductivity. The electronic structure calculation of Pd2NiTe2 suggests that its electrical conductivity is a three-dimensional one, which is caused by conduction bands originated from d orbitals of Pd and Ni and p orbitals of Te.
